VIVIANGLE.

SPECIFICATION forming part of Letters Patentl No. 421,144, dated February 11, 1890.

Application filed October 12, 1888. Serial No. 87,879. (No model.)

.To all whom it may concern.-

Beit known that I, FRANZ .IULIUS ROST, a citizen of the United States, residing' at Milwaukee,in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Mangles, of which the following is a full and clear description, reference being' had to the accompanying drawings, forming part of this specification, in which i Figure 1 is a sectional view of a mangle, showing my invention.- Figs. 2 to 4, inclusive, represent details to be referred to.

My invention relates to certain new and useful improvements in mangles; and it consists in the improved constructions and combinations of devices which I shall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention,I will now describe the same, and indicate the manner in which I carry the same out. v p

In the said drawings, A represents a snit-- able frame, within which the operative parts of my mangle are appropriately mounted.

B represents the cross-bar connecting the upper ends of the sides of said frame.

C C indicate the pressure-rolls.

G G are small rollers which bear upon the upper pressnreroll.

rE is the power-screw, and D is the platform or table upon which the goods are fed.

I employ in my machine extensions or leaves which are removably attached to the main frame, and said extensions are so formed in conjunction with said frame that they may be securely held in a horizontal position when desired, or may be suspended in the manner of a hinged leaf or extension, orbe entirely removed from the machine whenever desired. The constructions which permit these important results consist in forming each inner side of the frame with an overhanging flange a, having formed therein the opening o, the under surface of said flange adjacent to the opening being in the form of an inclined plane llc, as shown in Fig. 2.l The side pieces of the main frame are also formed with inclined portions at the points K, contiguous to the openings o in the flanges n, and said inclined portions are provided with curved seats p at the ends thereof, for a purpose I will nowexplain.

The leaves or extensions D have secured to the under sides castings N, which are provided with outwardlyproj ecting bolts or pins r and inclined lugs s, the former of which are designed to engage and rest upon the inclined portions K and to engage the seats p therein, and the latter (the lugs s) are designed to pass under the inclined portion 7c of the projecting flanges n to hold the extension in a horizontal position ready for use. In attaching these leaves or extensions to the frame of the machine the inclined lugs s are first passed into the openings o in the hanges n, with the pins or bolts 0' resting in the lower curved seats and against the shoulders t, formed by the frame. rlhe leaf is now forced backward, thereby causing the inclined lugs s to pass under the inclined portions of the flanges n, and also causing the pins or bolts to ride up the inclines K until they become seated in the seats at the top thereof. The leaf is now securely held in a horizontal position, as shown in Fig. 3. The leaf may be readily removed from the machine by pulling it forward, so that the incline K and that uponfthe lug s disengage and the lugs s align themselves with the openings 0, the pills or bolts r in the meantime riding down the inc lines K until the forward movement of the leaf is arrested by the shoulders t. In this position the leaf or leaves may be readily removed from the machine and packed away unt-il again needed.

Power to operate the machine may be transmitted in anysuitable manner, not herein necessary to describe or show.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, isM

In a mangle, the main frame having the inclines K, and having the side portions formed with overhanging flanges n and curved seats7 said flanges being provided with the openings o, in combination with removable extensions or leaves provided with projecting bolts or pins r, which rest upon the inclines K, and with inclined lugs s, adapted to pass under the inclines K of the flanges a, whereby tlie extensions or leaves are removably held, substantially as herein described..
